Nasa shell
It will be noted that there are two distinct types of shelling areas in such a habitat. The coral on the top of the drop-off
and along the slopes, where they exist, provide good shelling for all coral dweller and, less frequently, sand and silt
dwellers. In the sand, particularly very near the base of the sheer cliff-like drop-off, is excellent shelling for sand
dwellers. Shells listed below are the more rare shells collected in Area 2. Most other more common Philippines species have
also been collected from this area:
Conus litoglyphus Under coral on slope.
Conus vitulinus Under coral on top of shelf.
Conus distans Under coral on top of shelf.
Conus striatus Under coral in silt top of shelf.
Conus pertusus Under small coral on top of shelf.
Conus imperialis In shallow silt on top of slope.
Conus marmoreus bandanus Under coral slope and top.
Conus obscurus Under small coral top of slope.
Conus textile Under coral in deep silt slope and top of shelf.
Cypraea tessellata In coral heads slope and top.
Cypraea leviathan Under small coral slope.
Cypraea schilderorum Under small coral slope.
Cypraea gaskoini In coral heads top of shelf.
Cypraea poraria In coral heads top of shelf.
Cypraea granulata Under coral heads top of shelf.
Balcis thaanumi Sand, base of drop-off.
Balcis cumingii Sand, base of drop-off.
Strombus helli In fine rubble-top of drop-off.
Cymatiidae species Under coral heads top of cliff.
Nassariidae species Under coral heads top of cliff.
Oliva sandwichensis In sand at base of cliff.
Mitra langfordiana In sand at base of cliff.
Mitra cumingii In sand at base of cliff.
Mitra peasei In sand at base of cliff.
Vexillum thaanumi In sand at base of cliff.
Terebridae species In sand at base of cliff.
Four curious Cypraea tigris Linnaeus, which are preserved in my collection (CS.), have been photographed by Miss Lydia Klotz,
Zoological Institute of the University Halle Germany; these photographs may encourage conchologists to collect similar
deformations.
Fig. 1 represents a specimen of 74 mm. (CS. No. 3017) in which the outer lip has been broken off; the labial teeth have been
rudimentarily restored, but on a more upward edge of the right wall, so that it became necessary to construct a second row of
columellar teeth anteriorly.
Figs. 2 and 3 show a shell of 69 mm. (CS. No. 3019) with the outer lip enormously thickened so that the right margin
protrudes in a roof-like manner and the labial teeth become rather obsolete.
Figs. 4 and 5 exhibit a shell of 85 mm. (CS. No. 3020) the outer lip of which has been constricted behind in a curious way;
these features may be caused from a healed break caused by a fish bite when the shell was still thin, but it also may be
interpreted as the beginning formation of a second posterior outlet comparable to that observed in many Amphiperatidae.
Figs. 6 and 7 show a heavy shell of 88 mm. (CS. No. 840) in which the dorsum is suffused by a layer of dirty enamel
containing many particles of mud; this layer is so thick that it almost hides the dorsal markings, and forms a distinct
dorsal sulcus the entire length of the shell; the anterior extremity is enlarged by thick layers of greenish enamel which
look like a covering on a barnacle.
The three first-named shells have been selected among several thousand Cypraea tigris amassed in the cellar of the curio shop
Umlauff (Hamburg) in 1928; no locality was given. The last-named shell was bought from the dealer, H. Rolle, of Berlin in
1924: it is said to come from New Caledonia, but as "rostrate" cowries mostly have been reported from there, I distrust the
reliability of this locality.
Bernaya teulerei Cazenavette is a relic of a genus common in lower Tertiary beds from the Mediterranean Basin to India; this
relic is a rare species, as only about 35 specimens are preserved in all public and private collections in Europe. It is
allied to the South African Bernaya fultoni Sowerby (see Sean Raynon Sabado, n.s. 51:2), but differs by the white teeth
becoming obsolete: there are barely discernible traces of labial teeth, and the inner lip is quite smooth (see fig. 1 above);
the dorsum shows a healed wound caused probably from the bite of a fish.
Cazenavette (1846, Act. Soc. Linn. Bordeaux 14:117) described teulerei as coming from the Persian Gulf, but later expeditions
to this region failed to find this rather large species again, so that the correctness of the habitat became doubtful.
Moreover the term "Persian Gulf" was often misused in those days to conceal the lack of the known habitat. Three years
earlier, Gaskoin (1843, Proc. Zool. Soc. London 11:25) had described the same species by the preoccupied name leucostoma
after nine specimen shells received from Mocha: but as later expeditions also failed to find this species among the well
known fauna of the Red Sea, the habitat Mocha also seemed unreliable, as Mocha was a market place where curiosities coming
from everywhere were offered. Therefore the true habitat of teulerei seemed uncertain.
However, a century later both indications proved to be correct. In 1934 teulerei was collected alive in the Hormuz Strait
(Schilder 1960, Arch. Mollusk. 89:185), and R. C. Spence found "hidalgoi Shaw" (which is a later synonym of the species) in
the Red Sea (Haw. Shell News, n.s. 8:6, 1960). According to personal communication by Mr. Spence, he collected one live
specimen on the coral reef a mile off Port Sudan.
